DUST-PROOF JOURNAL FOR CULTlVATOR-DISKS.

SPECIFICATION forming part of Letters Patent No. 758,582, dated April26, 1904.

Original application filed May 18, 1903, Serial No. 157,567. No.177,107.

To all whom it may concern.-

Be it known that I, NATHANIEL S. BARGER, a citizen of the United States,residing in St. J oseph, county of Buchanan, .State of Missouri, haveinvented certain new and useful Improvements in Dust-Proof Journals forCultivator- Disks, of which the following is aspecification, referencebeing had therein to the accompanying drawings, in which Figure 1 is alongitudinal vertical sectional view; Fig. 2, a side elevation, and Fig.3 a vertical transverse sectional view taken on the line III IIIof Fig.1.

The main object of this invention is to provide a simple, durable, andeffective dustproof journal for cultivator-disks; and it consists in thenovel combination and arrangement of parts hereinafter described, andmore particularly pointed out in the claims appended.

Referring to the various parts by numerals, 1 designates'acultivator-disk provided at its center'with an aperture, in which isrigidly secured a hub 2. This hub is formed with a radial flange 3,which fits against the outer concave side of the disk and is riveted orotherwise rigidly secured thereto. A central longitudinal socket 1 isformed in the hub to receive the inner end of the spindle 5, saidspindle being rigidly secured in the socket by means of a transversebolt 6, which passes through that portion of the hub projecting beyondthe convex side of the disk and through the inner end of the spindle.Fitting the spindle is a journal-box 7, preferably of wood, and on theouter end of the spindle is rigidly secured a dust-cap 8, which isformed with an inward-extending dust-excluding flange 9, said flangeembracing the outer end of the journalboX and preventing dust or dirtentering between the journal-box and the spindle.

Embracing the upper side of the journalboX 7 is an arched bearing-block10, this block being formed at its inner end with a laterallyextendingflange 11, whose inner end extends beyond the joint between the hub andthe journal-box and prevents dust and dirt enter- Divided and thisapplication filed October 15, 1903. Serial (No model.)

ing-block is provided with a circular series of serrations 12, which areadapted to be engaged by a corresponding series of serrations formed onthe end of a supporting-bar 13. To rigidly clamp the journal-box 7 tothe bearingblock 11 and to the supporting-arm, I provide a vertical bolt14, which passes through the arm and the bearing-block and is formed atits lower end into a ring or yoke 15, which surrounds the journal-box.At the point where this ring or yoke passes around the journalboX thebearing-block is cut out slightly to permit said yoke to be drawn up bythe nut 16 to cause the journal-box to bind against the bearing-block onboth sides of the yoke. It will thus be seen that the single bolt 14clamps the journal-box to the bearing-block and also rigidly secures thebearing-block to the supporting-arm 13. By loosening the nut 16 thebearing-block may be adjusted to any desired angle with respect to thesupporting-arm and y then may be rigidly secured in its adjustedposition.

From the foregoing it will be readily seen that I provide an exceedinglysimple but durable dust-proof journal which may be readily adjusted toany desired angle. It will also be noted that when the woodenjournal-box becomes worn or broken it may be readily removed andreplaced by a new one by removing the cap 8 from the end of the spindle.This may be readily accomplished without disconnecting the disk from itssupporting-arm.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination of a cultivator-disk, a spindle secured rigidly atone of its ends to said disk, a journal-box loosely mounted on saidspindle, a dust-cap secured rigidly t0 the free end of the spindle andembracing one end of the journal-box, a bearing-block embracing theupper part of the journal-box and formed with a dust-excluding flangecovering the inner end of the journal-box, a supporting-arm and meansfor clamping together the journalbox, bearing-block and supporting-arm.

2. The combination of a cultivator-disk, a

hub secured to the center thereof, a spindle rigidly secured in saidhub, a journal -boX loosely mounted on said spindle and abutting againstthe inner end of the hub a dust-cap on the free end of the spindle andprovided with a dust-excluding flange which covers the outer end of thejournal-box, a bearing-block embracing the upper part of the journal-boxand formed with a dust-excluding flange which covers the joint betweenthe hub and the journal-box, a supporting-arm and a clampingyoke adaptedto secure together the journalbox, bearing-block and supporting-arm.

3. The combination of a cultivator-disk, a hub secured to the centerthereof, a spindle rigidly secured at one of its ends in said hub, ajournal-box loosely mounted on said spindle, a dust-cap detachablysecured to the outer end of the spindle and provided with adust-exeluding flange covering the outer end of the journal-box, abearing-block embracing the upper part of the journal-box and providedwith a dust-excluding flange covering the joint between the journal-boxand the hub said box being formedwith a circular series of serrations onits upper surface, a supporting-arm formed with a corresponding seriesof serrations, and a clamping-yoke adapted to secure together thejournal-box, bearing-block and supporting-arm.

4. The combination of a cultivator-disk, a hub secured to the centerthereof, aspindle secured at one of its ends in said hub, a journalboxloosely mounted on said spindle, a dustcap detachably secured to theouter end of the spindle and provided with an inward-extending annulardust-excluding flange embracing and covering the outer end of thejournal-box, a bearing-block embracing the upper part of the journal-boxand provided with an inwardextending dust-excluding flange covering thejoint between the journal-box and the hub, a supporting-arm, a ring-likeclam ping-yoke extending around the journal-box and formed with athreaded stem extending through the bearing-block and supporting-arm,and a nut screwed on the end of said stem whereby the journal-box andbearing-block may be clamped to the supporting-arm.

In testimony whereof I hereunto afiix my signature, in the presence oftwo witnesses, this 8th day of October, 1903.

NATHANIEL S. BARGER.
